How do you sort an array on multiple columns?

Question

I have a multidimensional array. The primary array is an array of

[publicationID][publication_name][ownderID][owner_name] 

What I am tryin

Answer 1

I suggest to use a built in comparer and chain the wanted sort order with logical or ||.

function customSort(a, b) {
    return a[3].localeCompare(b[3]) || a[1].localeCompare(b[1]);
}

Working example:

var array = [
    [0, 'Aluminium', 0, 'Francis'],
    [1, 'Argon', 1, 'Ada'],
    [2, 'Brom', 2, 'John'],
    [3, 'Cadmium', 3, 'Marie'],
    [4, 'Fluor', 3, 'Marie'],
    [5, 'Gold', 1, 'Ada'],
    [6, 'Kupfer', 4, 'Ines'],
    [7, 'Krypton', 4, 'Joe'],
    [8, 'Sauerstoff', 3, 'Marie'],
    [9, 'Zink', 5, 'Max']
];

array.sort(function (a, b) {
    return a[3].localeCompare(b[3]) || a[1].localeCompare(b[1]);
});

document.write('
');
array.forEach(function (a) {
    document.write(JSON.stringify(a) + '
');
});
